20099744 divided by 531 
We want to divide 20099744 by 531.

Advancing to step 1:
When dividing 2 by 531, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 531

On to step 2:
The number 531 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 531

On to step 3:
531 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 200 to get 200.
Fetch the next digit (9) from the dividend, attach it to 200 and continue: 2009 / 531

Advancing to step 4:
When dividing 2009 by 531, we get 3 with a remainder of 416.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 416 after subtracting 1593 from 2009.
Grab the next digit (9) from the dividend, add it to 416, then carry on: 4169 / 531

On to step 5:
The number 531 fits into 4169 7 times, leaving a remainder of 452.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 3717 from 4169 to get 452.
Grab the next digit (7) from the dividend, add it to 452, then carry on: 4527 / 531

Advancing to step 6:
If we divide 4527 by 531, we get 8 and a remainder of 279.
The next digit of our result is 8. 
Result so far: 378.0
Subtract 4248 from 4527 to get 279.
Include the next digit (4) from the dividend after 279, then repeat: 2794 / 531

On to step 7:
When dividing 2794 by 531, we get 5 with a remainder of 139.
Put 5 as the next digit of the answer. 
Result so far: 3785.0
Deduct 2655 from 2794 and we're left with 139.
Include the next digit (4) from the dividend after 139, then repeat: 1394 / 531

On to step 8:
When dividing 1394 by 531, we get 2 with a remainder of 332.
Record the quotient 2 as the next digit in the result. 
Result so far: 37852.0
If we take 1062 away from 1394, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 9:
If we divide 3320 by 531, we get 6 and a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 37852.6
The remainder is 134 after subtracting 3186 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
The number 531 fits into 1340 2 times, leaving a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 37852.62
Subtract 1062 from 1340 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 11:
When dividing 2780 by 531, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 37852.625
Subtract 2655 from 2780 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
531 can be fit into 1250 2 times, resulting in a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 37852.6252
Subtract 1062 from 1250 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 13:
When dividing 1880 by 531, we get 3 with a remainder of 287.
Put 3 as the next digit of the answer. 
Result so far: 37852.62523
The remainder is 287 after subtracting 1593 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 14:
2870 divided by 531 is 5 with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 37852.625235
Deduct 2655 from 2870 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 15:
When dividing 2150 by 531, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 37852.6252354
Subtract 2124 from 2150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 16:
The number 531 fits into 260 0 times, leaving a remainder of 260.
The next digit of our result is 0. 
Result so far: 37852.6252354
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 37852.6252354 with a balance of 2.6e-07.
